different between petaflop vs petascale
petaflop
English
Etymology
peta- +? flop
Pronunciation
- (Received Pronunciation) IPA(key): /?p?t?fl?p/
- (US) IPA(key): /?p?t?fl?p/
Noun
petaflop (plural petaflops)
- (computing) Either of two units of measure of the calculating speed of a computer:
- a quadrillion (10¹?) floating point operations per second.
- 1992 March 2, Richard Preston, The New Yorker, "The Mountains of Pi":
- ...a better machine is a petaflop machine. A petaflop is a quadrillion flops, a quadrillion floating-point operations per second, so a petaflop machine is a thousand times as fast as a teraflop machine, or a million times as fast as a Cray Y-MP8. The petaflop machine will exist by the year 2000, or soon afterward.
- 1992 March 2, Richard Preston, The New Yorker, "The Mountains of Pi":
- 1,125,899,906,842,624 (2??) floating point operations per second.
- 2012 Fall, Edgar Gabriel, COSC 6374 — Parallel Computation: Introduction and Organizational Issues, slide 20: “IBM Roadrunner”:
- First computer to surpass the 1 Petaflop (2?? FLOPS) barrier [in 2008]
- 2012 Fall, Edgar Gabriel, COSC 6374 — Parallel Computation: Introduction and Organizational Issues, slide 20: “IBM Roadrunner”:

petascale
English
Etymology
peta- +? scale
Adjective
petascale (not comparable)
- A metric for objects on the scale of quadrillions (1015 or 1,000,000,000,000,000) of elements. Most often used for computer systems; a petascale computer system operates at speeds measured in petaflops and has memory measured in petabytes.
